Router>en
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#router rip
Router(config-router)#version ?
  <1-2>  version
Router(config-router)#version 2
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.3.0
Router(config-router)#end

Router#ping 192.168.2.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.2.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

小结

注意RIP协议的包状态为:

1
2
3
4
5
6
Layer 7: RIP Version:2, Command: 2
...
Layer 4: UDP Src Port: 520, Dst Port: 520
Layer 3: IP Header Src. IP: 192.168.3.2, Dest. IP: 224.0.0.9
Layer 2: HDLC Frame HDLC
Layer 1: Port Serial2/0

是一个网络层的协议, UPD端口为520, destination是224.0.0.9, ripv2组播地址.
